The Javalambre Astrophysical Observatory (OAJ) has migrated to RedIRIS, i.e. it has been connected to the main scientific and academic centres in the country. This has taken more than a year of work and technological deployment. Much of the coordination and operation of the fibre has been carried out by CEFCA teams. A process that began in August 2021 with an agreement with this network, funded by the Ministry of Science, Innovation and Universities. A network that, with 500 affiliated centres, links universities and research centres throughout Spain.

The Observatory's communications infrastructure requires fibre optics to meet the high capacity, reliability, security, flexibility and control requirements common to research centres of its category, especially as a Singular Scientific and Technical Infrastructure (ICTS). At the same time, it seeks to favour collaboration between researchers and improve access to the data generated and instruments of the centre for the national and international scientific community.

Until now, the connection of the Observatory with the outside world was made with a two-channel radio link of 600MB/s bandwidth. In fact, it linked the OAJ with the Government of Aragon building in Teruel, which is directly linked to the Research Network of Aragon (RIA) node. A radio link that was also used for connection to both the internet and the telephone network, including control and operation networks. Adverse weather conditions affected communication and data transfer at times.

The Observatory and CEFCA are now connected at 100 Gbps, a speed more than 100 times faster than the previous radio link. The development of the project has taken almost a year of work, the main difficulty of which has been to bury the installation for some 30 kilometres. These sections correspond to the entrance to Teruel and areas that cross Manzanera, Arcos de las Salinas and Los Cerezos.

The infrastructure will also improve the fibre connection of many of the municipalities in the area, as the service companies will take advantage of these undergrounding works to install new communications to which the towns will be able to connect later. This was not one of the initial objectives of the project, but it will indirectly improve services and communications in these municipalities.
